Abstract

The invention relates to miniaturized non-magnetic double-axis turntable equipment indirectly driven by a worm gear and a worm. The equipment comprises a base, an inner frame, a load table top, an inner shaft system assembly, a trunnion system assembly, an inner shaft worm assembly and a trunnion worm assembly, wherein the load table top and the inner shaft system assembly are vertically connected to the inner frame; the inner shaft worm assembly is meshed with the inner shaft system assembly to transmit torque; the inner frame is horizontally connected to the base through the trunnion system assembly; and the trunnion worm assembly is meshed with the trunnion system assembly to transmit torque. The non-magnetic double-axis turntable equipment can realize accurate angular position movement of a load product in two degree-of-freedom directions of space rolling and pitching. According to the non-magnetic double-axis turntable equipment based on indirect transmission of the worm gear and the worm, micro-jitter interference of an electromagnetic field and a motor is avoided, manual carrying is facilitated due to the miniaturized design, and the functional test and verification requirements of inertial components under the non-magnetic condition can be met.

Description

technical field [0001] The invention relates to a nonmagnetic two-axis turntable device indirectly driven by miniaturized worm gears and worms, and belongs to the technical field of test simulation turntables. Background technique [0002] Due to the continuous development of inertial devices and the wide use of different application scenarios, the requirements for miniaturization, non-magnetization, and high stability of turntable test equipment are becoming more and more stringent. Therefore, there are requirements for the weight, size and transmission mode of the turntable test equipment. [0003] In the measurement process of inertial devices, traditional turntable test equipment is usually directly driven by electronically controlled servo, which is prone to electromagnetic field interference. After the electric turntable is precisely positioned, the electromagnetic induction of the torque motor will produce subtle vibrations, which will also cause errors in the measur...
